To all whom t may concern:

Be it known that GiLBER'r JACKSON, a citizen of the United States, residing at New York, in the borough of Manhattan and State of New York, have invented certain new and useful improvements in Bottle-Valves, of which the following is a specification. i

My invention relates to bottle valves, the primary object of which is to prevent the refilling of bottles after they have once been emptied, and embodies certain improvements in the construction disclosed in an application for Letters Patent iled by me April 23, 1913, Serial No. 7 63,124, renewed February 19, 1915, Serial No. 9419, as will be more definitely pointed out and claimed hereinafter, reference being had to the accompanying drawing, in which Figure 1 is a central vertical sectional view of my improved device, located in a bottle neck.

Figs. 2, 3 and 4 are transverse sections taken on the lines II-IL III-III and IV-IV of Fig. 1.

Fig. 5 is a detail side elevation of the plug of my valve.

Similar numerals of reference denote corresponding parts in the several views.r

In the drawing, the reference numeral 1 denotes the neck of an ordinary bottle, such as a whisky bottle, in which is disposed a casing 2, forming the discharge portion of the bottle, said casing being formed of any suitable material, such as glass, hard rubber, metal, or the like. Said casing is formed at itsl lower end into a valve seat 3, above which it is slightly enlarged to form a valve chamber 4, said chamber being eX- panded into a still larger chamber 5 eX- tending substantially to the top of said casing, and into which is removably disposed a plug 6 hereinafter to be described. The upper inner end of said casing is screwthreaded to receive the cap piece 7, which when screwed to position retains the plug 6 against movement. y

The plug 6 is formed with a series of wings 8 near its lower end, spaced apart, and contacting at their outer surfaces with the interior surface of the casing 2, the lower edges of said wings resting upon an annular flange 9 formed in said casing by making that portion of the interior of the casing above said flange slightlylarger in diameter than the portion below the same.

pin being freely movable vertically in said f recess 13, openings 16 being formed in the plug 6 from the upper end of said recess to the exterior.-` Disposed in the portion 4 of the casing 2 is a valve 17, the same preferably being formed hollow and closed at a its upper end by a screw-threaded cap 18, that is recessed centrally at 19 to receive the lower end of the pin 15, when the bottle is in a vertical position, as seen in Fig. 1.

The bottom face of the plug 6 is concaved i" at 20, and is provided on its sides with wings 21 to position it in the chamber 4, and at the same time leave a space therearound for the passage of the liquid when said valve is unseated. Disposed between said plug and thevalve 17 is a ball 22 freely movable in its space, said ball resting upon the upper face of the valve 17.

The operation of my improved construction is as follows With the bottle in the position shown in Fig. 1, the ball 22 rests upon the valve 17, and, by reason of its immediate proximity to the concaved lower end of the plug 6, it cannot be moved vvertically, nor can it move toward the center, because of rod 15, which rests with its lower end in aperture 19 in valve 17. Said ball thus acts as a stop to the opening of the valve 17, and while free to roll annularly in the chamber 5, can have no other movement. But when the bottle is inverted, the rod 15 and its weighted guide 14 will immediately move into the recess 18 in plug 6, thus leaving the ball 22 free to assume a position at the apex of the concaved undersurface of the plug 6, which will leave the valve 17 free to move away from its seat, so that the liquid in the bottle'may How therethrough and past the plug 6, through the spaces between the wings 8 and 10, and thence through the apertures 12 to the discharge point of the casing 2.

I have shown the valve 17 as formed hollow in order to reduce its weight, if made of rubber, metal, or the like, but the same may be made solid and formed of some material, such as wood, provided it is made of the proper weight. The valve seat 3 is constricted to form an opening only large enough to discharge a volume of liquid when the bottle is turned or tipped past a horizontal position that will be insuflcient to reseat the valve by flotation, so that it is necessary that the bottle be tiltedv past a horizontal position before the weighted rod l5 will move into the recess 13, and the valve be permitted to unseat.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

The combination with a bottle neck, of an upwardly opening valve therein, a plug disposed above said valve at a distance to leave a chamber therebetween and having its lower face cup-shaped, a ball in said chamber normally resting on said valve and litting between the same and said cupped surface at substantially the edge of the latter, a centrally disposed rod freely shiftable vertically in recesses in said valve and plug and acting when in its lowermost position to lock said ball between said valve and said cupped. surface and when shifted to its uppermost position by the inversion of the bottle permittingl said ball to seek the center of said cupped surface to permit said valve to open, and a weighted guide attached to said rod and movable in the recesses in said plug, said plug recess be ing apertured near its upper end to permit the escape of liquid entrapped therein when the bottle is inverted.

In testimony whereof I have hereunto set my hand this 22 day of March, 191.5.
